COMPOSITION FOR CLEANSING PAINTED SURFACES.

SPECIFICATION forming part of Letters Patent No. 723,089, dated March17, 1903. Application filed November 14, 19Il2. Serial No. 131,359. (Nospecimens.)

To all whom it may concern.-

don, England, have invented certain new and useful Improvements inCompositions for the Cleansing of Painted,Varnished, or PolishedSurfaces and the, Like, of which the following is a specification.

.This invention relates to a newer improved composition for thecleansing of painted, varnished, or polishedsurfaces and the like; andit has for its its object to provide a composition which being appliedto surfaces such as the outside or inside woodwork of railway or othercoaches or carriages, glass, stone, or other finished or polishedsurfaces will readily and completely remove any greasy, sulfurons, orother deposited matter therefrom, leaving the original surface intact,and which compositionat the same time shall not injuriously affect anymetal adjacent to or form-- ing part of snchsurface.

In carrying the invention into efiect we form a compound of lemons orlemons and oranges, limes, or similar acid fruits. It is preferable,however, where difierent kinds of fruitare employed that one-half of thetotal weight of fruit should be lemons. The next step in the formationof the compound consists in the pulping of the fruit, and this iseffected by the addition thereto of a small proportion of a mineralacid, preferably hydrochloricacid, and boiling with water. in a suitablevessel for a period sufficient to form a thick paste. By this time thegreaterpart of the mineral acid will have been driven off. A suitableproportion of oxalic acid is now added together with asufficientquantity of any form of syrup-such, for example, as blacktreacle,

molasses, golden syrup, glucose syrup, dextrine, flour, potatoes, or thelike. The mass is boiled and stirred until the desired degree ofviscosity is reached, being then of a thick tained is added when quitecold a small proportion of butyric or any other oil or grease dissolvingacid of the fatty series. For example, formic, propionic, lectic, oleic,or the like acid may be substituted for the butyric acid. The acid iswell stirred in, and the mixture, if desired, may be scented with someessential oil.

In order to adapt the composition to the various purposes for which itmay be employ ed, it is necessary that the degree of viscosity, as wellas the acidity of the said composition, be varied. This, as will bereadily understood, may be effected by varying the proportions of thevarious component ingredients.

A very suitable mixture for general use is made. by first boiling thefollowing ingredients in the proportions stated until a thick paste isformed: two pounds lemons, one pound hydrochloric acid, four poundswater. To the paste formed by theabove is added two pounds oxalic acid,three pounds black treacle. When cold, one fluid ounce of hutyric acidis well stirred in and so fficient water is added to make up one gallon.

In use the composition is applied by means ofa brush or the like to thesurface required to be cleansed and left thereon for a period varying inaccordance with the thickness,

age, and nature of the deposit to be removed.

The exact period may be ascertained by testing the efieot of compositionfrom time to time. When it is found that the full effect has beenattained, the composition is rubbed off, carrying with it theobjectionable matter, and the surface, if so desired, Washed with water.

In cases where it is desired to impart apolish to the cleaned surface aproportion of mineral oil not exceeding ten per cent. of the totalWeight is added to the composition.

Having now particularly described and ascertained the nature of the saidinvention and in what manner the same is to be performed, we declarethat what we claim isl. A compound for cleaning painted or polishedsurfaces, comprising a boiled pulp of acid fruit and a mineral acid,combined in suitable proportions with oxalic acid and a syrup, togetherwith a grease-dissolving acid.

2. A compound for cleaning painted or polished surfaces, comprising aboiled pulp of acid fruit and a mineral acid, combined in suitableproportions with oxalic acid and a syrup, together with agrease-dissolving acid and a mineral oil.

3. Acompound for cleaning painted or polished surfaces, comprising aboiled pulp of acid fruit and hydrochloric acid and Water, combined insuitable proportions with oxalic acid and a syrup, together with agrease-dissolving acid.

4. A compound for cleaning painted or polished surfaces, comprising aboiled pulp of acid fruit and hydrochloric acid and water, cornbinedinsuitable proportions with oxalic acid and a syrup, together with agrease-dissolving acid and a mineral oil.

5. A compound for cleaning painted or polished surfaces, comprising aboiled pulp of acid fruit, and a mineral acid, combined in suitableproportions with oxalic acid and black treacle, together with butyricacid.

6. A compound for cleaning painted or polished surfaces, consisting of aboiled pulp of lemon fruit and hydrochloric acid and water, combined insuitable proportions with oxalic acid, black treacle, butyric acid, anda mineral oil.

In witness whereof we have hereunto set our hands in the presence of twowitnesses. EDWIN JOHN WATKINS.
